Hamilton, who rode with Armstrong on the US Postal Service team, said he hopes Armstrong will now go to the USADA and give them "all the information they're asking for".

This thing is way bigger than Lance, the sport was super dirty back then.

"Lance needs to name names. We didn't do this by ourselves," he continued. "I feel like I've got a D on my chest for doper, I'll have that for the rest of my life".

Hamilton, who was stripped of his 2004 Athens Olympics gold medal over doping, said, "I saw it as cheating, that's how we're a little bit different. I was so scared I was going to get caught".

"He never put a gun to my head and said 'you have to do this', but obviously you felt pressured to perform", he explained.
